Finished the first bench this morning.
Not sure if I will be adding any more boards to either the seat or the back because right now - it's SUPER COMFORTABLE - beyond what one might think when looking at it. I mean, you'd have to experience it to really understand.
I did put a little angle on the back - maybe 15 degrees - and I think it made all the difference in the world - and was very easy to do, thankfully.
I like a little air flow aspect for the back. It supports what's needed.
I could probably take my palm sander and smooth off some of the edges. We'll see.
This bench is heavy - much more than the ones it will be replacing, so I'm hoping they will last longer. At some point I will paint them with something to help with weather wear. Have to wait and let the wood dry out some.
Thanks again for all the help!
